-You can also use [`nvshim`](https://github.com/iamogbz/nvshim) to shim the `node`, `npm`, and `npx` bins to automatically use the `nvm` config in the current directory. `nvshim` is **not** supported by the `nvm` maintainers. Please [report issues to the `nvshim` team](https://github.com/iamogbz/nvshim/issues/new).
